VARIETIES OF WHEAT
The Department of Agriculture reports
that the introduction of hard winter wheat
from Kussia into Kansas and other states of
the central Great Plains area in the early
seventies was an epoch-making event. The
growing of' these Crimean wheats, especially
the Turkey and Kharkov varieties, has been
the principal cause of the prosperous develop-
ment of much of that section. The develop-
ment and distribution of Kanred, an im-
proved strain of hard red winter wheat, may
prove equally epoch-making in the history of
Kansas. Kanred is one of the most impor-
tant examples of the improvement of wheat
by the method of pure line selection. It is
the product of a single head, selected in 1906
at the Kansas Agricultural Experiment Sta-
tion. Its true value was determined only
after many years of careful experiments, but
as a reward not fewer than 500,000 acres were
sown in the State of Kansas alone in the
fall of 1919. Since 1917, Kanred has been
under experiment in many states other than
Kansas. Last fall many thousands of bushels
were introduced into other states for com-
mercial growing. Kanred is unusually well
adapted to many of the varying conditions in
the state of Kansas. Its principal advantage
over Turkey and Kharkov is its resistance to
some forms of bo'th stem rust and leaf rust.
It "has other advantages, however, such as
slightly greater winter hardiness, earlier ma-
turity, and makes better pasture. Those fac^._
tors have caused it to outyield the Turkey
and Kharkov wheats in most sections of
Kansas by 3 to 5 bushels per acre. The same
factors may or may not be as important in
. To determine the varieties of Australian
wheat best adapted to conditions on the
Pacific coast, the United States Department
of Agriculture has conducted a series of ex-
periments which accurately ascertained the
yield and quality of those varieties already
of commercial importance in that region, as
well as other varieties, samples of which were
brought direct from Australia. In connection
with the latter phase of the investigation
more than 130 samples of wheat were ob-
tained, representing 92 distinct varieties.
Kesults from the early experiments with these
wheats show that the "Federation group,"
consisting of three varieties, Federation, Hard
Federation, and White Federation, is prob-
ably the best suited to this western region.
These three varieties were compared in
yield with the leading commercial wheats, in-
cluding the Bluestem, Australian varieties,
Pacific, White Australian, and Early Baart,
and produced higher yields, according to the
department's cereal specialists. Hard Feder-
ation produced the larger yields in Oregon,
while White Federation did better in Cali-
fornia. Milling experiments indicate that
Hard Federation is equal or superior for mill-
ing and bread-making purposes to the leading
commercial varieties now grown on the Pacific
coast and also superior in this regard to Fed-
eration and White Federation.
